Setup takes five minutes and it works out of the box.
Pros:
- Clean, modern web UI
- Built-in DoH/DoT/DoQ/DNSCrypt — no add-ons
- Per-client filtering rules
- DHCP server
- Parental controls + Safe Search
- DNS rewrites for local network
- Low resource usage (~60-80 MB RAM)
- Single container deployment
Cons:
- No built-in Prometheus metrics (uses custom stats API)
- No native multi-instance sync
- Smaller community than Pi-hole
Best for: Most users. The best balance of features, simplicity, and resource usage.

2. Pi-hole — Best Community
Pi-hole is the original self-hosted DNS ad blocker and has the largest community by far. It provides network-wide ad blocking with a detailed dashboard, query logging, and DHCP. It’s been the default recommendation since 2015 and has thousands of guides, integrations, and community-maintained blocklists.
Pros:
- Largest community (50K+ GitHub stars, 300K+ Reddit)
- Most third-party integrations
- Detailed query log dashboard
- DHCP server
- Extensive blocklist ecosystem
- Thousands of guides and tutorials
- Proven track record (since 2015)
Cons:
- No built-in encrypted DNS (needs Unbound or cloudflared add-on)
- No per-client rules without group management (less intuitive)
- Higher resource usage (~120-180 MB RAM)
- Larger Docker image (~300 MB)
Best for: Users who want the biggest community, most integrations, and don’t mind adding Unbound for encrypted DNS.

3. Blocky — Best Lightweight
Blocky is a YAML-configured DNS proxy that strips away the web UI to deliver the fastest, lightest DNS ad blocker available. It supports DoH/DoT natively, per-client filtering, DNSSEC validation, conditional forwarding, and Prometheus metrics — all in a 15 MB image using 30 MB of RAM.
Pros:
- Extremely lightweight (~30 MB RAM, 15 MB image)
- YAML configuration (version control friendly)
- Native DoH/DoT — no add-ons
- Built-in DNSSEC validation
- Built-in Prometheus metrics
- Multi-instance sync via Redis
- Per-client filtering in config
- Runs from scratch image (minimal attack surface)
Cons:
- No web UI (API only)
- Smaller community
- Requires comfort with YAML configuration
- No DHCP server
- Less third-party documentation
Best for: Infrastructure-as-code users, resource-constrained hardware, users who don’t need a web dashboard.

4. Technitium DNS — Best Full DNS Server
Technitium DNS is a complete DNS server that includes ad blocking as one of many features. It can serve as a recursive resolver, authoritative nameserver, DNS proxy, and ad blocker simultaneously. The web UI covers zone management, DNSSEC, clustering, DHCP, and all DNS protocols.
Pros:
- Full recursive DNS (no forwarding needed)
- Authoritative DNS zone hosting
- Split-horizon DNS
- DNS clustering (v14+)
- Built-in DoH/DoT/DoQ
- DHCP server
- Comprehensive web UI
- Two-factor auth on admin (v14+)
- Built-in backup/restore
Cons:
- Overkill for pure ad blocking
- More complex web UI (many options)
- Higher resource usage (~150-300 MB)
- Smaller ad-blocking community
- Single-developer project (though very active)
Best for: Homelabbers who want one tool for all DNS needs — ad blocking, zone hosting, recursive resolution, and infrastructure management.

How We Evaluated
- Ad blocking effectiveness — all use the same blocklist format, so effectiveness depends on lists, not software. Scored equally.
- Feature completeness — encrypted DNS, DHCP, per-client rules, admin features.
- Resource efficiency — RAM, disk, and CPU usage on typical hardware.
- Ease of setup — time from
docker compose upto blocking ads. - Community and documentation — guides, integrations, support resources.
- Maintenance burden — how much ongoing work each solution requires.
FAQ
Do these block YouTube ads?
Partially. YouTube serves ads from the same domains as content (*.googlevideo.com), making DNS-level blocking unreliable for YouTube specifically. All four solutions have this same limitation. For YouTube ads, use uBlock Origin in your browser alongside DNS blocking.
Can I run two DNS ad blockers for redundancy?
Yes. Run two instances (e.g., Pi-hole on one device and AdGuard Home on another) and set both as DNS servers in your router. If one goes down, the other continues blocking. For same-software redundancy: Pi-hole has Gravity Sync, Blocky has Redis sync, and Technitium has clustering.
Which blocklists should I use?
Start with these:
- Steven Black Unified Hosts — comprehensive, well-maintained
- Hagezi Pro — excellent balance of blocking vs. false positives
- OISD — curated, low false positives
All four solutions support hosts-format lists interchangeably.
Can I run this on a Raspberry Pi?
Yes, all four. Pi-hole was designed for Pi hardware. AdGuard Home and Blocky run comfortably on a Pi 4 or Pi 5. Technitium works on Pi 4+ (ARM64 required). A Pi is ideal — low power, always-on, dedicated.
What about Unbound?
Unbound is a recursive DNS resolver, not an ad blocker. Pair it with Pi-hole for recursive resolution + ad blocking, or use Technitium which has recursive DNS built in. AdGuard Home and Blocky forward to upstream resolvers (Cloudflare, Quad9) over encrypted DNS, which is simpler and nearly as private as running your own recursive resolver.
